Xinhui Grade 30 lightweight mullite brick uses high-purity refractory powders as the base material. It is formulated to a target bulk density and produced with organic composite pore-forming materials, vacuum extrusion forming, high-temperature sintering, and precision machining. The product balances lightweight insulation, high temperature resistance, and structural strength, suitable for thermal equipment with higher requirements for lining stability and energy efficiency.

Product Description:

Xinhui Grade 30 lightweight mullite brick uses a high-purity raw material system to reduce performance fluctuations caused by impurities. With a uniform pore structure, it has lower thermal conductivity and lower heat storage. It also provides good high-temperature volume stability and thermal shock resistance, suitable for hot-face or semi-hot-face conditions. Strict dimensional control and good machinability make on-site cutting and fast construction easier.

Product Features:

• Low heat capacity and low thermal conductivity, reducing heat storage loss for stable energy savings
• High purity and low impurities for better chemical stability
• High temperature resistance with direct flame contact
• High strength with excellent high-temperature volume stability, not easy to deform or crack
• Accurate dimensions, supports cutting and machining for higher construction efficiency
